problems with dental implants – why do dental implants fail?


Hi, it’s Adrian Kat from
Advanced Dental Artistry. What do you do when
a dental implant fails? Well, if you ask any experienced
clinician who places a lot of implants,
do all implants, are they all successful? Well, the answer,
of course, is no. When we look at research
done over decades, and you’re talking about
30 to 40 years, we know that the survival rate
for implants, although probably one of the highest in all dental
fields is around about 94 to 98%. Therefore, if we actually place
100 implants, we’re probably expecting around about a two to
six percent failure out of 100. So, the real problem is that there’s
two types of failures we see. One is latent failures that happen
many years after implants is actually placed and during
this time, usually, there’s two failures, of course. One is actually a cosmetic failure
where the gum tends to shrink around the implant or maybe
the bone starts to be lost around the implant and, cosmetically,
the implant doesn’t look great. And then there’s, of course,
situations where a patient may get, what we call, peri-
implantitis which is when they get, I suppose, the simplest
way to do it is gum disease around the implant and this
is actually quite rare. What I want to talk about today is when the failure happens
very quickly and this is, usually, in the first three months. And this is usually a biological
problem where the body does not accept the implant and
we get what we would term a rejection and, therefore,
the bone does not grow into the implant so there’s
no osteo-integration or that bone to implant interface. What will happen, actually, early
on, this will happen within the first three months of
placing an implant is that the soft tissue will start
to grow around the implant and this will actually lead
to a lot of bone loss. So, the most important thing
to do when an implant fails or when an implant
is actually placed is reviews. An implant has to be reviewed in
the first three months to ensure that it heals correctly. If there’s any signs that the
implant has not taken, the most important thing is to
remove the implant as soon as possible because
if the implant is left, more and more bone will be lost
and, therefore, there’ll be less bone in order to place an implant. I want to actually talk you
through a case, actually, today of Daniel who was actually a
heavy smoker and he had diabetes. So, he had already health issues
that actually limited the survival of his implants. When replacing all implant
treatment, it’s important to talk about risk factors to
patients and some of them can be health, some of it can be
certain things, for example, diabetes, if they smoke, it their health is actually
compromised and, of course, hygiene. There are certain things that will
actually limit the survival of implants and, therefore, the
survival rate or the success rate actually drops in these patients. If the patient understands these
risks and they’re still happy to go ahead with treatment, they have
to be aware there is a higher risk of an implant failing. So, in this case, you can see
that the implant has failed. We couldn’t actually see him for
around about six months because he worked away. So, at the three month mark,
we noticed that the implant hadn’t healed, he was a heavy
smoker, he had diabetes, and we basically said to him
that there’s a risk that this implant hasn’t taken. We, then, wanted to review him
about four weeks after but, unfortunately,
because he worked away, we probably didn’t see him for
around about five or six months. You can see, in this photo,
that we’ve got no bone surrounding the implant
on the x-ray. So, from here, the idea was
then to actually look at removing the implant because
he was an All-On-Four case, there was a failed All-On-Four
implant, it meant that the other three implants were successful
and fine but we had to remove this implant as soon as possible. So, on day of surgery, we’ve
actually got him back in here and we have had to remove the
implant and change the implant site slightly closer to the front
of the mouth, place a new implant that was
in the correct position for where his bridge was and
then re-engineer the bridge that he already had so that
he could have that fitted on the same day. It’s quite a complex process
to what you do and we did also bone graft where the site
of the old implant was in order to ensure that the bone
healed correctly, in this case. So, with all cases with failed
implants whether a single implant or especially on an All-On-Four case,
because All-On-Four implants must be healthy, the most important thing
is to act quickly. We must remove the implant
as soon as possible. We sometimes may need to
graft that site and there are, usually, situations where we can,
if we act quick enough, place a new implant in the
right position to reuse the bridge, that we don’t have to make a new
bridge for the patient. All cases with a failed implant
are very different and it’s important to understand
that although implants are very successful,
there are cases, unfortunately, where, biologically, the implant
doesn’t take and the implant must be removed. Of course, there may be cost
incurred in actually doing this treatment because it is
a revision of the case and this is something that
must be discussed. If you have any questions, please
give us a ring at 1800SMILING I look forward to, one day,
seeing you in the practice.

  1. Question I have diabetes type two does this means with this condition that implants is not recommended for this procedure and what other option is there beside removable dentures?

  2. Question what's the difference between having dental implants compared to just having dentures? And what is the difference in costs?

  3. So i have no baby teeth but in the past few years a whole tooth just kinda started growing in…kinda like a stray tooth. No pain or discomfort either but now the gum is receding just on the tooth is my body rejecting it? Theres kinda no space its just in front ,just there. It hasnt bothered any of my other teeth either.

  4. honestly it isnt necessary to ever show graphic bloody photos to joe public when it can be cleansed/filtered/animated and many of us really can't or rather not stomach more gore.
